High-Level Threshold Register (addresses 0x04, 0x0A, 0x10 and 0x16)
The High-Level Threshold Register contains the upper level value of the interrupt threshold for the comparator
filter. If the value of the comparator filter is equal to or above the high level threshold, the corresponding interrupt
flag is set (if enabled). Table 17 describes the High-Level Threshold Register.

DESCRIPTION
Unused. Always read '0'.
Unsigned high level threshold for the comparator filter output.
Low-Level Threshold Register (addresses 0x05, 0x0B, 0x11 and 0x17)
The Low-Level Threshold Register contains the lower level of the interrupt threshold for the comparator filter. If
the value of the comparator filter is equal to or below the low level threshold, the corresponding interrupt flag is
set (if enabled). Table 18 describes the Low-Level Threshold Register.
